How to Fix CVE-2026-33690

To remediate this vulnerability, upgrade all affected Wwbn/avideo dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

wwbn/avideo fixed: Latest secure release 
Upgrade wwbn/avideo to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for wwbn/avideo

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-33690, inspect your project dependencies for Wwbn/avideo:

inspect dependencies for wwbn/avideo

Analyze the terminal output to locate any version of Wwbn/avideo in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-348: Use of Less Trusted Source, where the product has two different sources of the same data or information, but it uses the source that has less support for verification, is less trusted, or is less resistant to attack. In Wwbn/avideo, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Summary The `getRealIpAddr()` function in `objects/functions.php` trusts user-controlled HTTP headers to determine the client's IP address. An attacker can spoof their IP address by sending forged headers, bypassing any IP-based access controls or audit logging. ## Vulnerable Code File: `objects/functions.php` ```php $headers = [ 'HTTP_X_REAL_IP', 'HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'REMOTE_ADDR' ]; foreach ($headers as $header) { if (!empty($_SERVER[$header])) { $ips = explode(',', $_SERVER[$header]); foreach ($ips as $ipCandidate) { $ipCandidate = trim($ipCandidate); if (filter_var($ipCandidate, FILTER_VALIDATE_IP, FILTER_FLAG_IPV4)) { return $ipCandidate; } } } } ``` ## Attack Scenario 1. Attacker sends request with forged header: ``` X-Client-IP: 127.0.0.1 ``` or ``` X-Real-IP: 192.168.1.1 ``` 2. `getRealIpAddr()` returns the forged IP 3. Any IP-based rate limiting, access control, or audit log that relies on this function is bypassed ## Proof of Concept ```bash curl -H "X-Client-IP: 127.0.0.1" \ https://target.com/any_endpoint.php ``` The server now believes the request came from localhost. ## Impact - Bypass IP-based rate limiting - Bypass IP-based access controls - Forge audit log entries - Potential privilege escalation if localhost is trusted
